SEIMIC MICROZONING
1) Knowledge of testing methods for soil and rock characterization in seismic areas by means of in field and laboratory tests.
2) Learning quantitative procedure to estimate co-seismic effects (local amplification, liquefaction, instability) to be used for drawing microzonation maps and to assess local seismic hazard and risk.
This module provides the students with operational methods and approaches for the surficial deposit characterization of their dynamic behaviors. They will enable the future geologists to measure and calculate the parameters needed to make quantitative estimations of co-seismic effects within the urban centers.
The multidisciplinary approach presented during the course enables the student to get independent in choosing and using the most effective testing methods according to the geological and lithological conditions of a site.
